Making your QTextBrowser show remote images

2007-05-08 21:05

It's re­mark­ably easy to turn your QTextBrows­er in­to a lim­it­ed web browser, at least good enough to show im­ages from the we­b.

Here's all the code:

from PyQt4 import QtCore,QtGui
import urllib, os, md5

class PBrowser(QtGui.QTextBrowser):
    def loadResource(self, type, name):
        url=unicode(name.toString())
        ret=QtCore.QVariant()
        if url.startswith('http://'):
            dn=os.path.expanduser('~/.bartleblog/cache/')
            if not os.path.isdir(dn):
                os.mkdir(dn)
            m=md5.new()
            m.update(url)
            fn=os.path.join(dn,m.hexdigest())
            if not os.path.isfile(fn):
                urllib.urlretrieve(url, fn)
            ret=QtGui.QTextBrowser.loadResource(self, type, QtCore.QUrl(fn))
        else:
            ret=QtGui.QTextBrowser.loadResource(self, type, name)
        return ret

And here's bartle­blog tak­ing ad­van­tage of it:

It even has a prim­i­tive cache and ev­ery­thing ;-)
